The lugs 30 are secured in the sockets 29 by stud bolts 32, as best shown in Figs. 2 and 4. The lugs, recesses and bolts are arranged so the shoes 31 can be easily placed on or removed from the outside thereof as related to the assembled tractor. That is, the term inside of the wheel is used to designate the side of the wheel adjacent the frame and the other the outside, as previously indicated.

The rim 26 has transverse recess passages 33 therein that are arranged centrally in the faces 27 and are inclined from the inner edge of the rim outwardly and inwardly toward the axis of the hub; and these passages are arranged under the shoes Bland centrally under the cog sockets 34 in the skeleton shoes. The passages 33 are arranged under thevopen ends of the cog-sockets 34 so dirt can be forced out of the sockets andthrough the passages when the cogs 35 of anf endless chain'36 enter the sockets. Inf other words, the purpose of the passages is to prevent ldirt from being packed in the cog-sockets 'theevent that it is carried to the drive nwheel by the endlesstrack chains, vas it will be when the tractoris used in loose soil such as a plowed field. v c

The shoes 31 are full skeleton form, as best shown in Figs. 8 to 11 inclusive, for the purpose of reducing the weight ofl thewheel, and they are formed with their outside walls smooth and i alignedso that the side-guards 37 on the chain 36 will be parallel with the sides when assembled and engage them to hold the chain on the Wheel when the tractor is beingv turned so that all the side thrust of turning is-not applied to the chain cogs. In other words,"the purpose of the guards 37 is to aid the cogs 35 in holding the chain centrally on the wheel when the tractor making short turns."

It is understood that the chain 36 forms no part of this invention further than that the wheel isconstructed to operate with a chain such as is shown in my plfior application forl United States Letters Patent on 'a tractor, Serial Number 637,051, filed October 10, 1932.

This chain is shown by dottd'lins in Figs. 3 and 7 for the purpose of illustrating how the co'gs 35 on entering the cog sockets 34will drive the dirt out of the sockets and through the passages V33, as indicated by the arrows in Figs. 3 and 5. By the foregoing means the cog sockets 34 in the shoes 3,1 are kept relatively clear of dirt which otherwise would pack in them if they didnot haveopen bottoms and by-passes from them. n

A gear housing 38 is secured to the inside Wall of the rim 26 by bolts 39 that extend entirely through the rim 26 and flange 40 that is integral with the housing.

An internal vgear 41 is integral with the housing 38, and also integral with this housing is an annular flange 42 that has its open end'closed by a disk mud-guard 43 that is held from rotation and centrally therein by brackets 44 that are secured to the mud-guard 43 and'frame 17, as best shown in Figs. 1 and 3. In'fFig. 3 the space 45 that is shown between the Vrim o f the mudguard43Y and the inside Wall of the annular ange 42 is exaggerated as to size for the purpose of illustration. 4In, actual practice lthere isha very close fit between the rim of the guard and inner wall of the flange to exclude the dust and dirt from the gear housing. Also there is an opening 46 through the disk for the hub 15 and also another opening 47 for the drive shaft 48.

A pinion 49 in mesh with the gear 41 is secured to shaft 48 so that when the shaft 48 is driven `the tractor wheel will be driven by the pinion 49 and gear 41.

By the foregoing construction and arrangement of parts the gear drive of the tractor wheel is effectively guarded against dust and dirt.

In use the wheel is driven as fully described, and also its cog sockets are kept clean and its gear drive protected from dirt and dust as fully described.

I claim as my invention:

1. A tractor wheel including a rim having flat peripheral faces and also having passages therein that are arranged transversely and inclined relative to the faces of said rim, shoes mounted on said rim, and means detachably securing said shoes to said rim, and said shoes having open bottom sockets therein 'that are in register with said passages so that material inclined to clog said sockets can be forced out of them through said passages.

2. A tractor wheel including a rim having flat peripheral faces and also havingpassages therein that are arranged transversely and inclined relative to the faces of said rim, skeleton shoes mounted on the rim, and means detachably securing said shoe to said rim, said shoes having open bottom socketstherein that are in register with said passages so that material inclined to clog said sockets can be forced out of them through said passages. l

A3. A tractor wheel including a rim having a plurality of flat peripheral faces thereon and with passages arranged centrally and transversely therethrough and inclined thereto, shoes for said faces that have open bottom sockets therein that are adapted to be in register with said passages, and screw bolts for detachably securing said shoes to said rim to hold said sockets in register with said passages said shoes Secured so they are removable and replaceable from the outside of said tractor wheel.

4. A tractor wheel including a rim having a plurality of flat peripheral faces thereon, recess passagesarranged centrally and Atransversely in said faces and inclined thereto, pairs of lug sockets in said rim adjacent the outside edge thereof, skeleton shoes for said faces that have openbottom cog-sockets therein that are in register with said passages, pairs of lugs on said shoes for said pairs of lug sockets, and stud bolts for detachably securing said lugs to said rim.

5. A tractor wheel including a hub, a rim, a disk integral with and interposed between said hub and rim, a plurality of flat peripheral faces to said rim, passages arranged centrally and transverselyin said faces and inclined from the inner edge of said rim outwardly and inwardly toward the aXis of said hub, pairs of lug sockets in said rim adjacent the outer edge thereof, skeleton shoes for said faces, open bottom cog sockets in said shoes that are in register with said passages, pairs of lugs for each of said shoes that are adapted to be tted into their respectivepairs of lug sockets, and stud bolts for securing said lugs to said rim.
